随着现代社会的发展,排水系统在处理城市居民生活污水和工业废水上起到越来越重要的作用。污废水在输送和处理过程中,污染物质会发生转化,并生成新的物质。其中生成的H_2S气体便是一种非常有害的物质,一方面它在H_2S杆状菌的作用下,在管道表面被氧化成H_2SO_4侵蚀内管壁的混凝土表面及其他设施;另一方面,在运行维护中发生H_2S泄漏,极易造成H_2S中毒伤亡事故。
With the development of modern society, the drainage system plays an increasingly important role in the treatment of domestic sewage and industrial wastewater of urban residents. Wastewater in the transport and handling process, pollutants will be transformed, and generate new substances. The H 2 S gas generated therein is a very harmful substance. On the one hand, it is oxidized into H_2SO_4 on the concrete surface of the inner pipe wall and other facilities under the action of H_2S bacilli; on the other hand, H_2S leak during maintenance can easily lead to H_2S poisoning accidents.
